Have been using the Epson RD-1 for over a year now and am very pleased with the result, works well with all the M lenses, except the ultra-wide VC 15mm lens, which shows a very high amount of vignetting. The overall feel and weight of the RD-1 is just right. Can't wait to hold the RD-1s to check out the updated software. Would like to hear from anyone who has laid his/her hands on the Epson RD-1s.
